Hi My 2009 1 series 116i sport today failed its emission test on mot. I am looking for any advice from any owners with similar issues. I had a replacment coilpack fitted 2 months ago when engine mgt light came on. This fixed the issue then however I am concerned that the faulty coil has caused damage to the cat on the car. My local indy garage suggested I try fuel additives first before replacing any parts - o2 sensor first and so on. The car has only done 22,000 miles. Thought this was good when I bought the car now thinking the low mileage may have contributed to the problem. Has anyone got any advice? andyelisa
